Inner planets are rockier and outer planets are gaseous. Hope this helps! Can I have brainliest please
Answer:
D - Hydroxide Ion (OH-)
Explanation:
A base provides either hydroxide ions (OH–) or other negatively charged ions that combine with hydrogen ions, reducing their concentration in the solution and thereby raising the pH. In cases where the base releases hydroxide ions, these ions bind to free hydrogen ions, generating new water molecules.
Answer:
1. increase the temperature
2. increase the concentration of reactants
3. increase the surface area of the reactants
4. use a catalyst
5. remove the product as it's formed
Explanation:
for a chemical reaction to take place, the bonds between atoms in the reactants are broken, the atoms rearrange and new bonds between the atoms are formed to make the products.
Answer:
Hope this helps kinda got confused mid way
Explanation:
So the hydrogen sulphide is H2S for the molecular formula. Then the mass of hydrogen sulphide would be 1×2+32= 34g/mol At STP.
Answer is 456 mmHg.
<em>Explanation;</em>
This is a simple unit conversion problem.
1 atm = 760 mmHg
Hence,
0.600 atm = (760 mmHg
/ 1 atm) x 0.600 atm
= 456 mmHg
Pressure can be measured by using many units such as atm, Pa, torr, bar, cmHg, mmHg and so on.
The relationships among those units as follows
1 atm = 101325 Pa = 1.01325 bar = 760 torr, 760 mmHg = 76 cmHg
